Galvanized hollow sections are a widely used material in modern construction, applied in various building projects, machinery manufacturing, road construction, bridge construction, shipbuilding, and other fields.

In the oil and gas extraction industry, two types of pipelines are indispensable: tubing and casing. These two types of pipelines play a crucial role in the extraction process.

In the machinery manufacturing industry, there are many methods for forming thick-walled seamless tubes, but few processes truly benefit enterprises in terms of efficiency, cost, and quality.

The national standard thickness of stainless steel pipes should first be determined by the nominal diameter or outer diameter of the pipe.

In automobiles, there's a material that may go unnoticed, but it's crucial—like the car's "blood vessels" and "skeleton," supporting the powertrain and ensuring safety.

304 stainless steel pipes are well known for their durability and resistance to corrosion, but they are not completely immune to rust. If they are handled or stored carelessly, rust spots can still appear.
